GEORGE H. GUMBEL, OF BROOKLYN, NEW YORK.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed January 14, 1909.

Patented Feb. 8, 1910.

Serial No. 472,302.

To all whom it may concern:

Be it known that I, GEORGE H. GUMBEL, a citizen of the United States,residing at Brooklyn, in the county of Queens and State of New York,have invented a new and useful Improvement in Non-Refillable Bottles, ofwhich the following is a specification.

This invention relates to a non-refillable bottle, and the object of theinvention is a bottle of this type which is easy of construction, andwhich can be manufactured by the ordinary processes of manufacturingbottles, and also by the average glass bottle manufacturer.

The invention consists in a bottle having a downwardly tapering neckwithin which is seated two separate ball retaining devices cooperatingtogether to permit outflow of the contents of the bottle and to preventtampering with the ball valve which prevents refilling.

The invention also consists in the novel features of constructionhereinafter fully described, pointed out in the claim and shown in theaccompanying drawings, in which:

Figure 1 is a vertical section through the neck of the bottle, and theball retaining devices. Fig. 2 is a section on the line 2-2 of Fig. 1.Fig. 3 is a perspective View of the upper portion of the retainingdevice. Fig. 4 is a perspective view of the lower member of the ballholding device.

In these drawings 1 represents the bottle neck which tapers slightlytoward the bottle and which is provided with an annular recess 2 midwayits ends. A split spring ring 3 is fitted in the recess 2, the lowermarginal portion of said ring being bent inwardly as shown at 3*. Alower retaining member 4 is of glass and fits snugly in the lowerportion of the neck. This member is provided with a beveled valve seat 5surrounded by a vertical flange 6 which is cut out at intervals as shownat 6 to permit passage of the liquid through it. The upper member of theretaining device is also of glass and consists of a ring 7 within whichis arranged a glass sleeve 8 secured to the ring by arms 9, the sleevebeing spaced from the ring, and this sleeve has a solid top and opensdownwardly. The sleeve is of much greater length than the width of thering and below and spaced from the ring the sleeve is surrounded by acomparatively thick flange 10, the lower edge of which is undercut asshown at 11. The ring 7 is provided with a beveled circumferentialgroove 12. A ball valve 13 fits in the seat 5 and works in the cageformed by the flange 6 and the sleeve 8.

When the parts are assembled in position, the bottle being first filled,the lower member 4: is passed through the spring ring 3 and into thelower contracted portion of the neck where it becomes wedged, and theupper retaining member is then put into position covering the lowermember 4 and the ball 13. \Vhen in position, the inwardly bent portion 3of the spring 3 extends into the groove 12 of the ring 7 and looks itagainst withdrawal. The sleeve 8 rests upon the flange 6, and theundercut flange 10 overhangs and guards the openings 6 cut in the flange6 and through which the liquid escapes. The upper member not only looksthe lower member in position but also pre vents the insertion of a wireor other instrument for the purpose of tampering with the ball valve 13.

WVhat I claim is:

The combination with a tapering bottle neck, of a ball retaining devicefitted in said neck, said device having a valve seat formed therein, acut flange inclosing said seat, a downwardly open sleeve resting on saidflange, an overhanging flange carried by the sleeve, said overhangingflange overlapping, but being spaced from the flange first mentioned,arms carried by the sleeve, a ring supported by said arms, the ringbeing grooved, and a split spring ring carried by the bottle neck, thesaid ring being bent longitudinally and its lower portion extendinginwardly into the groove of the first mentioned ring.
